gases therein; The release of such gases and consequent operation of thealarm may be controlled from the dash or steering post orfrom any otherconvenient part of the car.

AnOther'Ob ect of my invention is the provision of means for blockingthe valve 1n openposition, which is advisable when the car is left onthe roadway unattended and non-operating.- The effect of the valve being blocked open under such circumstances is to give an alarm as soon asthe engine is started, and in the event of the same being started by aperson designing to steal the car the operation of the engine blows thealarm and thus the legal custodiatior:

the car is notified of the attempt to steal the same.

Another object of my invention is to utilize the priming cup boring of acylinder for the connection of the alarm valve and to make provision ina convenient place in connection with said valve to utilize the primingcup taken from its boring.

Other objects of the invention will be apparent in the description takenin connection with the drawings ofwhich Figure 1 is a side elevation ofmy alarm attached to one of the cylinders of an automobile;

Fig. 2 is a plan view of the same;

Fig. 3 is a front elevation view of my valve showing the connection forthe priming cup;

Fig. 4 is a side elevation of my valve;

Fig. 5 is a cross section of the same taken along the lines 5-5 of Fig.4; and

Fig. 6 is a cross section taken along the lines 6-6 of Fig. 3, thisfigure showing the valve in blocked position.

Referring now in detail to the drawings 1 represents an alarm, whistleor horn and 2 is the valve through which the same is operated. Thisvalve consists of a casing specification of Letters Patent.

Patented oct. '7, 191a Application filed April 16, 1917. Serial at.$162,276;

3 a valve stem 4 provided with a valve head 7 This valve head isnormally held in the valve seat 8 by reason of the action of the spring9 acting between the top of the casing- 3 and the pin 15 projecting fromthe sides of the valve stem 4 at its upper end. The valve stem 4 is sofitted in the casing, 3 as to provide a space 10 between the valve stemand the casing, which space communicates with the conduit 11 which inturn communicates with the alarm 1. The valve" is provided with abifurcated lug, 12 whiclrrockably' supports the rocker arm 13 having theangle piece 14 integral therewith. v

The valve is fitted into a cylinder of an automobile engine by removingthe priming cup which connects with such cylinder and screwingthe valveinits place as is shown in'Fig. I have provided a coupling 16 connectingthe same with the valve assembly forthe purpose ofihaving screwed there-111 13118 priming cupremoved from the cylinder for the purpose ofattaching the valve thereto. In Fig. 1 "my device is shown in operativeposition, the priming cup being designated as The device is operatedfrom the dash, steering post or other conthrough the valve through theconduit 11 and into the alarm 1 thus sounding the same.

When a car embodying my device is left unattended with the power shutoff, the ring 19 is manually moved from the position shown in Fig. 4 tothe position shown in Fig. 6, which holds the lever 14 away from the lug12 and causes the rocking lever 13 to depress the valve stem 4 and holdthe valve head 7 away from its seat, thus maintaining while the ring isin this position open communication between the cylinder of the engineto which the device is attached and the alarm whistle or horn 1. It willreadily be seen that upon starting the engine while the ring 19 is inthe position shown in Fig. 6 that gases passing from the cylinder towhich the said device is attached will be forced between the valve headand valve seat through the conduit 11 and into the sounding element 1,and thus give an alarm that the motor has been started. If the motor hasbeen started by some one not authorized to start the same, the alarm isintended for the owner or person charged with the possession of the car,who can then promptly act accordingly. 7

' In order to remove the ring from the position shown in Fig. 6, thering is manually shifted over the projection or nose 20, over the lever14 to the position shown in Fig. 4 where it is held at the bottom ofsaid lever by the enlarged portion at the end thereof. hen the ring hasbeen moved to this position, the valve head 7 is seated so that no gasesare permitted to communicate with the sounding device 1 until the cord18 attached to the lever 14 is pulled to depress the valve head 7.

In the above description and the accompanying drawings I have shown thepreferable embodiment of my invention but I do not wish to be confinedto the disclosure therein contained, but what I desire to cover byLetters Patent is set forth in the appended claims.

Claims:

l. In an automobile alarm, a sounding device having a housing, a valvestem, a valve head integral with said valve stem, and a valve seat, saidvalve head being normally seated in said valve seat, a lug connectedWith said housing, an angle rocker arm rookably supported in said lug,one end of said angle rocker arm being adapted to Copies of this patentmay be obtained for depress said valve stem and unseat said valve head,a shiftable ring on sald angle rocker arm adapted to be positionedbetween said lug and the elbow of said rocker arm and thereby hold thesaid valve head in unseated position, said angle rockerarm beingenlarged at one end so as to prevent said shiftable ring from fallingtherefrom.

2. In an automobile alarm, a sounding de vice having a housing, a valvestem, a valve head integral with said valve stem, and a valve seat, saidvalve head being normally seated in said valve seat, a lug connectedwith said housing, an angle rocker arm rockably supported in said lug,one end of said angle rocker arm being adapted to depress said valvestem and unseat said valve head, a sliiftable ring on said angle rockerarm adapted to be positioned between said lug and the elbow of saidrocker arm and thereby hold the said valve head in unseated position,and a projection extending from said angle rocker arm for the purpose ofholding said ring against easy manipulation on said angle rocker armwhen said ring is positioned between the elbow, said angle rocker armand said lug, said angle rocker arm being enlarged at one end so as toprevent said shiftable ring from falling therefrom.
